I almost prepared the floor from inside for primer/painting. The holes for rustproofing are visible on the next pictures (some were cut on the spots for patching).
Table of Contents
Front Side


Exactly under the gas pedal there is a little hole, covered with a little plate (point welding).

There are 11 holes for rustproofing of the front cross member. The last hole on the left is cut and will be drilled in the new patch.
Middle Side



The big hole is for the cross member, the small one is for the rocker panel. The same holes on the other side are cut.

Back Side


These holes are for the new 1.1 gas tank.
More info about these holes in Butt Welding Lesson.



The big hole almost in the middle of the trunk is for the trunk of 1.1 i think.


These 2 holes (on the back panel) have their mission, but it is unknown for me. I will use them for rustproofing.

In general the floor is in very good condition.
God bless our deeds.
